ORGAN-VALVE.

To all whom, it may concern Be it known that I, WILLIAM E. PILOHER, acitizen of the United States, residing at Louisville, in the county ofJefferson and State of Kentucky, have invented certain new and usefulImprovements in Organ- Valves, of which the following is aspecification.

This invention relates in general to valves for wind instruments such aschurch organs, and more particularly to what may be termed a doublevalve or valve for alternately closing two separate ports. Its object isto render such a valve more quickly responsive to pneumatic action inperfectly closing either of the said ports.

To this end my invention consists in the construction and combination ofparts forming an organ valve, hereinafter more fully described andparticularly stated in the claims, reference being had to theaccompanying drawing in which;

Figure 1 represents a pneumatic motor in vertical section showing avalve according to my invention. Fig. II is a plan view of the valve.

Numeral i represents a pneumatic motor or other air chamber for organs,having two ports, 5, 6, each for both entry and exit. A valve, 7, facedas usual with a packing of sheet material such as soft sheepskin, 8, issecured upon the bottom, 9, of the motor to cover, alternately, theports 5 and 6. The packing, 8, is glued or otherwise firmly secured tothe valve at the ends, 10 and 11, and to the bottom of the motor at 12,centrally between the ports. This central attachment forms the hinge onwhich the valve rocks, and the packing is not attached to the valve inthe immediate region of this hinge.

Specification of Letters Patent.

Application filed March 10, 1913.

Patented July 15, 1913.

Serial No. 753,345.

The under side of the valve is formed as two planes meeting at an obtuseangle at the hinge line, 12, in order that the valve may rest true uponthe seat around each port in turn; and the packing, when stretched fromend to end over this central, downward angle, perfectly closes each portin turn. This arrangement of valve, packing and valve seats securesperfect flexibility at the hinge and renders it more reliable and moredurable than the packing would be if stiifened by rigid attachment tothe valve at or near the hinge.

I claim 1. In an organ valve, an air chamber having two ports in itsside; a valve having two faces adapted to alternately rest upon theseats around the said ports, and a packing of sheet material secured tothe valve at its ends and secured to the side of the chamber between theports as a hinge for the valve, but not secured to the valve near thehinge.

In an organ valve, an air chamber having two ports in its side; a valveshaped to alternately engage the ports, and a packing of sheet materialsecured to the side of the chamber midway between the ports as a hingeto the valve, and secured to the valve beyond the ports but not in theregion of the said hinge.

In testimony whereof I a'HiX my signature in presence of two witnesses.
